  • Number of Memory Slots4x288pin (DDR5)
  • Ready for advanced AI workloads with Intel Core Ultra Series 2 processors
  • Robust 16+2+1+2 teamed power stages deliver stable performance
  • Future-proofed connectivity via Thunderbolt 4 and 10Gb plus 2.5Gb Ethernet
  • Exclusive AI Overclocking, AI Cooling II and NPU boost technologies
  • Server-grade IPMI remote management with onboard AST2600 BMC controller

AI workstation foundation

This motherboard targets developers and researchers building systems for local AI inference and training workloads. It pairs Intel Core Ultra Series 2 processors with the connectivity and power delivery those workloads demand. The board suits professional workstations rather than consumer gaming builds.

Power delivery and expansion

Sixteen plus two plus one plus two teamed power stages feed the LGA 1851 socket through ProCool II connectors. Two PCIe 5.0 x16 slots and four M.2 sockets, one at PCIe 5.0 and three at PCIe 4.0, provide the bandwidth ceiling for accelerators and fast storage.

Remote management and I/O

An onboard AST2600 BMC with dedicated LAN enables server grade IPMI control and out of band monitoring via ASUS Control Center Express. Front panel USB 20Gbps, Thunderbolt 4, 10Gb and 2.5Gb Ethernet round out the high speed I/O for cluster integration.

Questions about this item

What does the 16+2+1+2 power-stage design mean for an Intel Core Ultra Series 2 processor in daily use?

The 16+2+1+2 teamed power stages deliver stable current to the CPU socket, helping the processor sustain high frequencies during heavy AI or compute workloads.

How does the PCIe 5.0 interface on the primary expansion slot and M.2 affect real-world throughput?

The PCIe 5.0 x16 slot and one PCIe 5.0 M.2 socket run at 5.0 speeds, enabling the latest graphics cards and fastest solid-state drives to operate at their rated bandwidth.

What physical clearance and mounting features should I check before installing this ATX board in my chassis?

The board follows the ATX form factor, includes SafeSlot reinforcement on the top PCIe slot, and uses M.2 Q-Latch screws for tool-free drive installation.
